Application filed March 25, 1922. SerialNo. 546,560.

particularly to brushes of that type having' bristle holders providedwith a plurality of nipples forming` sockets in which the bristle tuftsare secured.

One object of my invention to secure or fasten each tuft of bristles inthebristle holder by a staple haring its prongs clinched against theback of the holder, thus providing a separate fastener for each tuft ofbristles and avoidinga continuous and unbroken fastening wire asheretofore eniployed in brushes of this ojeneral type, with n the resultthat the bristles may be secured more tightly in the holder andfastened. with much more ease and dispatch than with the single wire asheretofore.

Another object of my invention is to direct the pointed ends of thestaple prongs, on being clinched, against the back of the bristle holderand into the material of the holder so as to secure not only ananchorage for the clinched ends of the staples to hold them againstlateral movement.y but also to effect a tight drawing action on thebristle tufts into the nipples or sockets 'in which :i5 `they aresecured.` and thus hold the bristles tightly in place.

rlhe invention consists further in the matters hereinafter described andmore particularly set forth in the appended claims.

.In the accompanying` drawingsy Figure 1 is a top plan view of abrushenr bodying the features of my invention;

Fig. 2 is an enlarged fragmentary top plan view of one of thelongitudinal bars of the Fig. 3 is a longitudinal vertical sectionalview taken on line 3-3 of 2; andl Figs. 4 and 5 are transverse verticalsec-` tional views taken on lines 4--4- and 5 5,

The brush shown in the drawings has a back in the form of an open frame1,l from one end of which projects a handle 2. The latter is in theplane of the back and is preferably made integral therewith bypcastwhich form between them bars k5 inwhich the'tufts of bristles 6, 6 aresecured inaccordancewith my invention. Each bar 5 has a row ofdepending` nipples 7 forming sockets to receive thetufts of bristles 6.rlhe back 1 beingin the forni` of an open frame, and the bristle holder3 being slotted. allows holding lthe brush under `a faucetand runningwater through the brush for cleansing the bristles and keeping` thebrush clean and sanitary. l g

For securing `the tufts of bristles 6 in' the sockets formed by thenipples` 7,y 7 l-provide for each tuft of bristles a securing memberinthe form of a staple 8. As shown in the drawings, each tuft ofbristles is `doubled on itself to form a loop 9 at gthe folded end ofthe tuft. staple 8 is engaged with the loop 9 in the bristle tuft andboth are inserted into` a nipple 7 with the prongs 11, 11 of the-stapleprojecting beyond the bristle tuft.l Each bar has a plurality ofapertures or holes 12, 12. one for each `of the nipples 7 on' the bar 5.Y end into its associated nipple yand at its upper end into a groove 13in the upper surface of the vbar 5 and common to all yofthe nipples onsaid bar.

ln inserting each staple 8 into a nipple' 7, its prongs 11 are passedthrough the aperture 12 of that nipple and project into and above the`groove 13; The upper ends of the prongs 11, 11 are then bent orclinched against the bottom ofthe groove 13 on opposite sides of theaperture`12-- ln clinching' theprongs, the pointed ends thereof are`directed downward. againstthe bottom ofthe groove 13 and are impingedor embedded in the metal of the bristle holder,` as shown in lligrsand.i 5

The pointed ends of theprong's 11, 11 being' in contact with thebars' 15onopposite rll'he looped portionf10 of the Each aperture 12 opens at itslower i sides of the aperturesr 12 and curved' downof theprongs downwardinto engagement with the bars prevents downward movement of the staples8 to loosen the bristle tufts engaged thereby. Also the staples 8holding the folded portions 9'` of the bristle tufts 6 tightly againstthe ends of the nipple sockets holds the staples against upward movementand this is further guarded against by reason of the fact that thelooped portions 10 of the staples in securing the bristle tufts in'placeare widened out to an extent greater than the apertures 12, as shown inFig. e.

ByA the construction described, there is a separate fastener for each ofthe bristle tufts 6; thus` avoiding the use ofy a continuous andunbroken wire engaging all of the bristle tufts distributed over theentire surface' of the'bristle holderas heretofore. This "is lanadvantage in that the fastening ofthe bristle tufts in the nipples maybe facilitated by requiring' only the tightening of each fastener inplace, and the tightening' effect of one fastener is not: dependent onthe tension put on another as with a continuous strand of; wire asheretofore.

Moreover, by having a separate fastener for each bristle tuftl, thevariation in the material may be readily compensated for by tighteningthe particular fastener. Then again, the factthat the pointed ends ofthe staple prongs ll are impinged against Vor embedded in'y the metal ofthe 'bristle holder prevents the staples'from creeping while the brushis inl use and thus holds the bristles tightly in place.- Moreover, theprongs of the staplesibeing turned down toward the body of the brushholder effects a tight fastening of the bristles'in placeas heretoforementioned. Also the pointed ends ofthe prongs being embedded in themetal of the bristle holder prevents the possibility of the prongsprojecting' beyond the bristle holder to scratch'tlie hand or catch intheclothing of the user of the brush.

After the bristle tufts 6, 6 are anchored 'or fastened'v inl the nipples7, 7 by the staples 8, 8, the outer ends 14 of the nipples are bent o'rswaged inward'y against the bristles, yas

shownin the drawings and more particularly` in Figs. 3 and if thereof.This aids in clamping the bristles in the nipples 7 and thus co-operateswithl the staples 8 in securing. t-hel bristles tightly in place."The'outer -end of the left-hand nipple 7 in Fig. 3 is shown inv dottedlines 1'5 before being bent i-Irw'ard `v against the tuftl of bristlesin that nipple.

I= claim as-In'y invention:

1..A bristle holder, comprising a body portion having: bristle receivingsockets; said holder having apertures extending therethrough intosaid-sockets, folded tufts of bristles in said sockets, and a separatestaple for fastening each bristle tuft in its socket, said staplesengaging the folded portions of the bristle tufts and having theirprongs extending 'through said apertures, the prongs of said staplesbeing clinched against the `side 'of the holder opposite said socketsand having their pointed ends embedded in the same on opposite'sides ofsaid apertures.
